Hessey's in Liverpool is long gone. Only ever bought a couple of things from them, as they were too expensive for my pocket at the time, but tons of drool-worthy gear. Famed for where The Beatles bought some of their equipment.
There used to be another shop on Woolton Road IIRC, but I can't recall the name.
Curley's was always my favourite when it was on Stanley St. (next door to Hessey's, and round the corner from Probe Records), always used to have a good selection of basses in. They're still going, now on Renshaw St. where Taskers used to be.
